Aerosol spray can induced cold injury in a patient with Raynaud's phenomenon

A 42-year-old woman with idiopathic Raynaud's phenomenon developed localized necrosis of her fingertip after using an aerosol can of spray hair color. Laboratory measurements indicated that while such products did not achieve freezing temperatures, they did become cold enough to potentially produce vasospasm. Patients with Raynaud's phenomenon should be cautioned that use of some aerosol products may result in a cold induced injury.
